ABSTRACT={The purpose of this technical note is to set down the mathematics of
perspective transformations, the natural first-order approximation to the picture-taking
process. There seem to be just two general questions: (1) What is the image
of a point in space seen by a camera, and (2) What is the ray in space corresponding
to a given image point? The answers to these two questions, together with a
number of applications, are given below. },
